Week 17 – The Sine Law and Cosine Law

Near the end of this Semester, we learned to solve triangles that don’t involve right angles. At first to me, it was really frustrating that I can’t use the Pythagoras Theorem since there were no right angles, but… Read More

Week 15 – Rational Equations

This week we’ve learned to solve rational equations, which is essentially solving unknown variables, but rather being more complicated since those equations can appear in different forms, such as adding/subtracting and multiplying/dividing. And the answer might even end… Read More

Week 14 – Rational Expressions (w/ non-permissible values)

This week we’ve learned to solve certain types of rational expressions. A rational expression is when a fraction’s numerator and denominator are both polynomials and doesn’t have any roots or any unknown variables as an exponent, e.g. Also, a… Read More

Week 13 – Graphing reciprocal functions

This week we’ve gone through even more about graphing, and I’ve learned how to graph reciprocal functions slopes over normal linear and parabolas. (I feel like there’s never an end to graphing knowledge, or is there?) In below… Read More

Week 12 – Absolute Value Functions

This week we’ve learned about another Function pattern. Rather than just Standard, Factored and General forms we came across functions involving Absolute values, and what it does it kind of interesting. An absolute value is a distance or… Read More

Week 11 – solving systems of equations by graphing

This week our class continued even more on quadratic equations (I believe it’s the 3rd chapter that has something to do with quadratics already), and I had learned how to solve 2 types of equations (linear-quadratic and quadratic-quadratic) graphically…. Read More

Week 10 – My reflection on the Midterm Exam

The midterm exam was finally over, although I only focused on chapters which I don’t have a firm memory on. In the end, I still got an A, which was somewhat surprising to me, and I’ve thought about why for… Read More

Week 9 – Maximum revenues

In this week’s Math 11, we’ve learned the relations between the revenue formula and quadratic equations (in regards of solving word problems, and to be honest I never expected it to appear this early rather than in an economics class)…. Read More

Week 8 – Quadratic functions [y=x², y=a(x-p)² +q], and changes in various ways

A (not so) short summary of what I’ve learned about the changes of Quadratic functions this week: On : -any vertical translation of the graph is dependant on: (if q is a positive number, the graph moves up… Read More

Week 7 – Discriminants

This week, we learned about Discriminants, which is really important in determinating if a quadratic expression has any roots, or if they have none at all. In this example the question also asked about how many roots are… Read More
